Specifies an output destination by associating (or disassociating) an emitter with (or from) a component or the default emitter
list.

Inherit emitters from parent.
|
| 1
|
Do not inherit emitters from parent. This is ignored if bit 0 is set, or if the default emitter list is specified.

- Bits 2-27
- Reserved for future use. Must be 0.

|
emitter-name is null-terminated.

Meaning
|
| 0
|
component-id is a pic x(4) comp-5 tracer handle returned from a call to CBL_CTF_TRACER_GET.
|
| 1
|
component-id is a pic x(n) text string. The termination character for the string is defined by bit 30.
|
-
component-id
- Component identifier. This is either a pic x(4) comp-5 tracer handle (from CBL_CTF_TRACER_GET) if bit 31 of
flags is not set, or a pic x(n) text identifier if bit 31 of
flags is set.
-
emitter-name
- Space- or null-terminated (depending on the setting of bit 28) case-insensitive property whose value is to be returned.

move "RTS" to component-name

Comments:
CBL_CTF_DEST provides equivalent functionality to the mftrace.dest and mftrace.dest.component-name configuration file entries.
There is always at least one entry in the default emitter list. When the last entry is removed from the default list, the TextFile emitter is implicitly added to it. If a component's emitter list becomes empty, it implicitly inherits its parent's emitters even if bit 1 of flags is set indicating that it does not inherit.
